To (kill wiwm it "may coat-em:

Be it known that I, WILLIAM H. BROWN, of Syracuse, in the county ofOnondaga and time of New useful Recording-Machine, of which thefolloiting is a specification.

My invention relates to recording machines, and has for its object theproduction of a particularly simple abdeflicieht'tecording elementtherefor; and it consists in the combinations and constructionshereinafter set forth and claimed. I I

In describing this invention, reference is bad to the accompanyingdrawing, in which like characters designate corresponding parts in allthe views.

Figures 1 and 2 are elevatione partly in section, of one form ofnijy'recordin mechaniszn, movable parts thereof bcinglsllown in l as intheir normal or starting positions, and in Fig. 2 as in their positionsas-' sumed when cooperating with each other. Figs. 3 and 4 arefragmentary views of oppo'eite edge portions of the i'ecordin element.Figs. 5, 6 and 7 are views simi or to Fig. 1 of modified constructionsof this recording mechanism The preferable embodiment of a record ingmechanism embodying my invention comprises a movable recording element1, having gear teeth provided with printing characters thereon; meansfor'holding the recording element in its normal or starting posit-ionmeans for limiting the movement of said element to different positions agear 2 for meshing with said gear teeth, and means; 3 for" supporting arecord-receiving element 4 upon which impressions are made by theprinting characters.

Preferably, the recording element 1 comprises a Wheel loosely mounted ona suit able horizoi'ltal' support or axle 5 vand having a series ofperipheral gear teeth extending partly around the same, a number orone'set of said teeth 6 being provided with raised printing characters7, as 0, 1,2,3,ctc;,at their ends, and others of said teeth constitutinganother set being unpro'vidcd with printing characters one of the latterteeth, as 8, being shorter than the teeth 6 andnormally air; rangedatthe printing point. Said element 1 is usually provided with anindicating surface 9 located about diametrically opposite to the seriesof teeth 6, and provided with characters corresponding to the printingAs will Fig. 2, i.

f characters 7 at the ends of said teeth, so that i when anypredetermined printing character as 5, is at the printing point, thecorrespond- Yoi'ln have invented a new and 5 mg indicating character, as5, will be dising element. To facilitate the reading of the indicatingcharacteraafixed plate 10 is arranged iii-proximity to the edge of therecording element 1 at the left-hand side thereof, and is provided witha slot 11 with which is registered the indicating charactercorresponding to the character at the printing point.

, The portion of the recording element or Wheel 1 provided with the 8-,is usually weighted,.an Wheel 1 is normally arranged with the greaterpart of such Weighted portion above andat the right hand of the axis ofsaid wheel, and, consequently, this Weighted portion normally tends tolnovc the element 1 in the direction. indicated by the arrow 1. beapparent to those skilled in the art, the element or wheel '1 may bemoved in the reverse direction by hand or by any suitable mechanism, notillustrated.

The means for holding the recording ele ment 1 in its normal position,comprises a stop 12 which may be moved laterally or otherwise, from itsnormal position relatively to the recording element 1 to release saidelement. This stop preferably engages with a peripheral shoulder 13 onthe element 1, the outer end of such shoulder be ing shown as locatedfarther from the axis of the recording element 1 than the outer ends ofthe teeth 6, in order to avoid engagement of the stop 12 by the teeth 6.on the return movement of the recording element. It, will be understood,however, that ptolvidi'ng the stop 12 is held in'its position assuzliein e-., out (of the path of the shouder 18, during the return of therecording eleear teeth 6 and the element or ment, it is not necessarythat said shoulder I *project a greater distance beyond the periphery ofthe, recording element than the teeth 6. Although the stop 12 isparticularly applicable for use with the recording element 1 it will beobvious that any other suitable means may be used in lieu thereof.

The means for limiting the movement of the recording element atpredetermined points or positions in its path of movement in order toposition predetermined charac tors at the printing point, may consist ofan adjustable shoulder 1 1 carried by a suitable support 15 andadjustable relatively thereto in a curved line concentric with therecording element 1, said shoulder 14: being preferably movable in acurved guide in the suptrolled by the keys of a recording machine,-

but as I do not wish to limit my present invention to any particularmechanism for effecting or controlling the movement of the stop 14, Ihave deemed it unnecessary to illustrate and describe such mechanism.When adjusted along the support 15 the stop may be held in position byany suitable means, as a screw movable in a slot in the support 15, butI do not limit this invention to any particular means for holding thestop 14: from movement relatively to said support. It will be apparenthowever, to those skilled in the art that the shoulder 14: is only lmallyspac'ed apart therefrom, said drum one exemplification of means forlimiting the movement of the recording element, an that any othersuitable mechanism may be used for this purpose.

i The gear wheel 2 for meshing with the gear teeth of the recordingelement 1, is

normally out of mesh with such teeth, and

is movable toward and from'said element 1 into and out of mesh' with thegear teeth thereof. This wheel 2 is carried "by any suitable movablesupport 16, and whenengaged with the teeth of the recording element 1,is revolved or advanced by said element. Preferably, the wheel 2 is oneof a train of calculating wheels and, upon making' a completerevolution, serves to advance another wheel of such train a single step.It is obvious, however, that the gear 2 may be any toothed element, theextent of movement of which depends upon the movement of the primaryactuating element, as the wheel 1.

The means 3 for supporting a record-receiv ing element 4:, may be of anysuitable construction, and is here shown as a revoluble drum or platenopposed to' the gear teeth of the recording element 1, and nor.-

being carried by a suitable support 17 and movable toward and from therecording element into and out of engagement with the character 7 at theprinting point. Pro viding the member 1 has not been advanced from itsnormal or starting position at the time the means 3 is moved toward thep'i'intpoint, no impression will be made upon.

36 coacts with a therecord-receiving element .4, as the short too; 118will be opposed to said means 3.

in operation, the stop 14 is adjusted to one of its various positions,and the shoul; der 12 is moved to its position illustrated in Fig. 2 forreleasing the recording element 1, whereupon said element advances underthe influence of its weighted portion until limited by the stop let.During the advance movement of the recording element 1, the gear 2 anddrum 3 remain in theirvnormal positions, as shown in Fig. 1,'butpreliminary to the retrograde movement of. said element 1, therecord-receiving element 4 is moved into and out of its position shownin Fig. 2 for eiiectin theprintingthereon by the character at theprinting point, and

the gear 2 is moved into the position shown in Fig. 2, so that it willbe advanced'upon the return movement of the recording ele ment 1. Afterthe. element 1 has been re'- turned to its normal or startingposition,the gear 2 is disengaged therefrom and moved to the position assumedin-Fig. 1.

In-Fig. 5, the recording element is shown as a sliding rack 18 having aseries of gear teeth 19 similar to the teeth 6 and 8 of the recordinface corresponding to the teeth 19, is nor--' mally held from'downwardmovement by a pivoted pawl 21, movable by any suitable element 1. Thisrack 18 is pro-- vided with stop-shoulders 20 on its rear means, andcoacting with the shoulders 20,- a

and when freed from the pawl 21 is limited in its downward movement atpredetermined points or posit-ions by an adjustable stop 22 adjustablealong a support 23. After the adjustable stop 22 limits the downwardmovement, ofthe recording element, the

pawl 21 returns to its position for-holding said element in its adjustedposition.-

I In Fig."the recording element '1 is illus- I trated' as an {arc-shapedrack 24. carried-by the free, end of a rock-arm 25; loosely j.

mounted at its opposite end'on a. shait 26w Said rack 24 is held'in itsvarious positions movement when free from the pawl 27 a-stop 28 movablealong a convex su port 29, Fig. 7 shows a recordin "me'mb sistin lot awheel 30 movab e in one direcby a. pivoted pawl 27 and is limited'in-"its tion a out its axis by a spring 31, and hav- 1 mg peripheralteeth 32 similar to the teeth 6 and 8 previously described, and aseries. of stop-shoulders 33 located about diametrically opposite to theteeth 32. A pivoted pawl 34:- coacts with the shoulders 33 to hold: thewheel 30 in its-adjusted position, and a stop 35 adjustable along acurved support peripheral. arm 37 on the wheel 30 for limiting themovement of, said wheel when free. from the pawl 34.

What I claim is 1 A movable "reeording element for cording machines,said element having a- 2. A recording element for recording inachines,said elementoscillating about a substantially horizontal axis, andhaving a series of peripheral gear teeth for engaging a toothed element,the teeth being provided with printing characters at their ends, andsaid recording element also having a weighted portion extending aboveand at one side of its axis, and overbalancing the opposite portion ofsaid element for ad'- vancing the recording element by gravity,substantially as and for the purposedcscribed.

3. A recording element for recording nia ines, said element oscillatingabout a subfiantially horizontal axis, and having itspper portionweighted and provided with a series of peripheral gearteeth for engaginga toothed element, the teeth having .vdrinting characters at their ends,and the greater part of such weighted portion being above and to oneside of the axis of said recording' element, substantially as and forthe purpose specified.

4. A. gear Wheel having two sets of peripheral teeth for engaging anintermeshing gear, one set of said teeth being provided with printingcharacters; and the other set being unprovided with printing characters,substantially as and for the purpose described.

5. In a. recording machine, the combination of a movable recordingelement. having f gear teeth, a number of the teeth being pro- Evidedwith printing characters for being successively advanced to printingposition, and another of the teeth being unprovided with a printingcharacter, and being at the printing position, and a toothed element forcooperating with said gear teeth, substantially as and for the purposeset forth.

6. A gear wheel-having a part of its pean inter-meshing gear, aplurality of such teeth carrying printing characters, said wheel havinganother portion of its periphery provided with a stop projectingtheredescribed.

T. In combination in a recording pachine, a recording element movableabout an axis, and havin peripheral gear teeth for engaging a toothedelement, the teeth. extending partly around the recording element, saidrecording element also having a peripheral shoulder, the outer endthereof bein located vfarther from the axis of the recording ele mentthan the ends of the teeth. and means normally cooperatin with the outerend of the peripheral shouder for preventing advancing movement of therecording element, substantially as and for the purpose set forth.

In testimony whereof, I have hereunto signed m name in the presence oftwo attesting witnesses, at Syracuse, in the county of Onondaga, in theState of New York, this 12th day of December, 1908.
